ASSEMBLY PROCEDURES
Drive shaft to engine (Fig. 1)
Loosen tube locking bolt (1) about ten turns so that the bolt point
will not obstruct drive shaft tube to be inserted. When inserting drive

When it is hard to insert drive shaft up to the marked position on
the drive shaft tube, turn drive shaft by the cutter mounting end
clockwise or counter-clockwise. Tighten tube locking bolt lining
up the hole in the shaft tube. Then tighten clamp bolt securely.
Cutting attachment to drive shaft (Fig. 2)
Loosen tube locking bolt (3).

on the drive shaft tube, turn attachment clockwise or counter-
clockwise. Tighten tube locking bolt lining up the hole in the
shaft tube. Then tighten clamp bolt (5) securely.
Installation of support handle (6) (Fig. 3)
